First had a Phone Screen and second had a STAR method interviews. Very good experiences for both interviews. I was interviewed following the career fair at my university. I was considered for various rotational roles at Caterpillar

First interview was through recruiting at my college. I was then invited for onsite interview with three engineers. Very nice and professional. They had you use the STAR format when answering questions and all were behavioral. Gave me a tour of the office after.
